5617c05d44 usb: fixes for v4.11-rc4
f_acm got an endianness fix by Oliver Neukum. This has been around for a
 long time but it's finally fixed.
 
 f_hid learned that it should never access hidg->req without first
 grabbing the spinlock.
 
 Roger Quadros fixed two bugs in the f_uvc function driver.
 
 Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather
 difficult to trigger. When we're dealing with bounced EP0 requests, we
 should delay unmap until after ->complete() is called.

8cb2cbae45 extcon: int3496: Add GPIO ACPI mapping table
In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.

Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

3ad33ae2bc drm: Add SCDC helpers
SCDC is a mechanism defined in the HDMI 2.0 specification that allows
the source and sink devices to communicate.

This commit introduces helpers to access the SCDC and provides the
symbolic names for the various registers defined in the specification.

V2: Rebase.
V3: Added R-B from Jose.
V4: Rebase
V5: Addressed review comments from Ville
 - Handle the I2c return values in a better way (dp_dual_mode)
 - Make the macros for SCDC Major/Minor more readable, by adding
   a 'GET' in the macro names

This adds the the devicetree binding for the Prefetch Resolve Gasket,
as found on i.MX6 QuadPlus.
The PRG is fairly simple in that it only has a configuration register
range and two clocks, one for the AHB slave port and one for the AXI
ports and the functional units.

The PRE connections need to be described in the DT, as the PRE<->PRG
assignment is a mix between fixed and muxable connections.

The Prefetch Resolve Engine is a prefetch and tile resolve engine
which prefetches display data from DRAM to an internal SRAM region.
It has a single clock for configuration register access and the
functional units. A single shared interrupt is used for status and
error signaling.

The only external dependency is the SRAM region to use for the
prefetch double buffer.

1ea3576874 drm/doc: Consistent kerneldoc include order
First overview text (if there is any), then headers (since generally
you want to start out with the data structures), then all the other
stuff with functions.

Most of this is pre-shpinx, since with the old docbook only the
overview stuff was pulled in directly. Everything else was put in a
per-section index, so include order didn't really matter.

b93658f83f drm/doc: Document drm_file.[hc]
Well, mostly drm_file.h, and clean up all related things:

- I didnt' figure out the difference between preclose and postclose.
  The existing explanation in drm-internals.rst didn't convince me,
  since it's also really outdated - we clean up pending DRM events in
  the core nowadays. I put a FIXME in for the future.

- Another FIXME is to have a macro for default fops.

- Lots of links all around, main areas are to tie the overview in
  drm_file.c more into the callbacks in struct drm_device, and the
  other is to link render/primary node code to the right sections in
  drm-uapi.rst.

- Also moved the open/close stuff to drm_drv.h from drm-internals.rst,
  seems like the better place for that information. Since that section
  was rather outdated this amounted to full-on rewrite.

A big missing piece here is some overview graph, but I think better to
wait with that one until drm_device and drm_driver are also fully
documented.

It wasn't clear if the 'forwarding' setting needs to be enabled on the

packets are forwarded to, or both.

In fact (according to my code reading) the setting is relevant on the
interface that packets are received from, so this change updates the doc

dd0db88d80 userfaultfd: non-cooperative: rollback userfaultfd_exit
Patch series "userfaultfd non-cooperative further update for 4.11 merge
window".

Unfortunately I noticed one relevant bug in userfaultfd_exit while doing
more testing.  I've been doing testing before and this was also tested
by kbuild bot and exercised by the selftest, but this bug never
reproduced before.

I dropped userfaultfd_exit as result.  I dropped it because of
implementation difficulty in receiving signals in __mmput and because I
think -ENOSPC as result from the background UFFDIO_COPY should be enough
already.

Before I decided to remove userfaultfd_exit, I noticed userfaultfd_exit
wasn't exercised by the selftest and when I tried to exercise it, after
moving it to a more correct place in __mmput where it would make more
sense and where the vma list is stable, it resulted in the
event_wait_completion in D state.  So then I added the second patch to
be sure even if we call userfaultfd_event_wait_completion too late
during task exit(), we won't risk to generate tasks in D state.  The
same check exists in handle_userfault() for the same reason, except it
makes a difference there, while here is just a robustness check and it's
run under WARN_ON_ONCE.

While looking at the userfaultfd_event_wait_completion() function I
looked back at its callers too while at it and I think it's not ok to
stop executing dup_fctx on the fcs list because we relay on
userfaultfd_event_wait_completion to execute
userfaultfd_ctx_put(fctx->orig) which is paired against
userfaultfd_ctx_get(fctx->orig) in dup_userfault just before
list_add(fcs).  This change only takes care of fctx->orig but this area
also needs further review looking for similar problems in fctx->new.

The only patch that is urgent is the first because it's an use after
free during a SMP race condition that affects all processes if
CONFIG_USERFAULTFD=y.  Very hard to reproduce though and probably
impossible without SLUB poisoning enabled.

This patch (of 3):

I once reproduced this oops with the userfaultfd selftest, it's not
easily reproducible and it requires SLUB poisoning to reproduce.

    ---[ end trace 9fecd6dcb442846a ]---

In the debugger I located the "mm" pointer in the stack and walking
mm->mmap->vm_next through the end shows the vma->vm_next list is fully
consistent and it is null terminated list as expected.  So this has to
be an SMP race condition where userfaultfd_exit was running while the
vma list was being modified by another CPU.

When userfaultfd_exit() run one of the ->vm_next pointers pointed to
SLAB_POISON (RBX is the vma pointer and is 0x6b6b..).

The reason is that it's not running in __mmput but while there are still
other threads running and it's not holding the mmap_sem (it can't as it
has to wait the even to be received by the manager).  So this is an use
after free that was happening for all processes.

One more implementation problem aside from the race condition:
userfaultfd_exit has really to check a flag in mm->flags before walking
the vma or it's going to slowdown the exit() path for regular tasks.

One more implementation problem: at that point signals can't be
delivered so it would also create a task in D state if the manager
doesn't read the event.

The major design issue: it overall looks superfluous as the manager can
check for -ENOSPC in the background transfer:

	if (mmget_not_zero(ctx->mm)) {
[..]
	} else {
		return -ENOSPC;
	}

It's safer to roll it back and re-introduce it later if at all.

db6ccf23e8 docs-rst: automatically convert Graphviz and SVG images
This patch brings scalable figure, image handling and a concept to
embed *render* markups:

* DOT (http://www.graphviz.org)
* SVG

For image handling use the 'image' replacement::

    .. kernel-image::  svg_image.svg
       :alt:    simple SVG image

For figure handling use the 'figure' replacement::

    .. kernel-figure::  svg_image.svg
       :alt:    simple SVG image

       SVG image example

Embed *render* markups (or languages) like Graphviz's **DOT** is
provided by the *render* directive.::

  .. kernel-render:: DOT
     :alt: foobar digraph
     :caption: Embedded **DOT** (Graphviz) code.

     digraph foo {
      "bar" -> "baz";
     }

The *render* directive is a concept to integrate *render* markups and
languages, yet supported markups:

* DOT: render embedded Graphviz's **DOT**
* SVG: render embedded Scalable Vector Graphics (**SVG**)
